Koalas were re-introduced to the Narrandera area in1972. More than 45 years on, the numbers are still increasing and it is clear that the original Koalas have bred successfully. The forest which hugs the Murrumbidgee River provides an ideal diet of River Red Gum leaves for koalas. The forest has been subject to both flood and fire during the past 5 decades. Despite this, it is now colonised by upward of 200 healthy Koalas. It is clear from the number of sightings both upstream and downstream of the original koala reserve, that the territorial habits of the koala have led to a spread of the population well beyond its boundaries. This project aims to record the presence and movements of this population.
